摘要
讨论复杂区域上非粘性型流体力学方程的谱元方法逼近．利用Ｌ２－Ｈ１型速度一压力变分形式证明Ｂａｂｕｓｋａ－Ｂｒｅｚｚｉ＇ｓＩｎｆ－ｓｕｐ条件被满足，并借此提出了适定的谱元逼近格式．
A spectral element appoximation of inviscid equations in complex geometries is presented. Using L2- velocity and H1- pressure weak formulation, it is proven that the wellknown Babuska Brezzi's Inf-Sup condition holds, and furthermore that the discrete problem is well-posed.
